King Zhou of Shang was bewitched by the fox demon Daji, which led to the prevalence of evil spirits and the people's misery. Yuanshi Tianzun then refined the Hunling Pearl to help Zhou defeat King Zhou. His disciple Taiyi Zhenren assisted the Hunling Pearl to reincarnate in the Li Mansion and was named Nezha. When Nezha was 17 years old, he saw Li Jing catching a demon and angrily broke up with his father. His mother, Madam Yin, died unexpectedly at the hands of a demon, which made him lose all hope. Nezha sacrificed himself to save the people of Chentangguan.
